Absolutely.
He built at Gillotts.
He was one of the best London builders equal to Ron Cooper -
I have always had a soft spot for the fillet brazed frames he made under his own name, all the ones I’ve seen pics of are in that blue too. One sold recently on eBay for a pittance.
Crazy.
Philbrook was known for his slimmed-down lugs tho, wasn’t he? He was a superb builder.
